If tt - all f1 = tt (tall) Addition rule- probability of two or more mutually exclusive events occurring (cid:862)either(cid:863) (cid:862)or(cid:863: tt x tt, what is the prob of each genotype, tt = 1/4 (tall, tt = 1/4 (tall) #expected for all classes tt = 1/4 (tall: tt = 1/4 (short, what is the prob of a tall plant, 1/4 (for tt) +1/4 (for tt) + 1/4 (for tt) = 3/4 (tall is tt or tt!) Chi-square (x2) test- used to determine the probability that the difference between the observed and the expected values is due to chance.
